To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...
the effect of late planting heat stress on yield and yield components was studied in 11 barley lines from icarda and one cultivar from iran (izeh) during two years (2005-2007) in gachsaran dry-land agricultural research station. each line was planted in a 6-rowed plot at two dates: normal planting (middle of november) and late planting (end of december) with three replications using a randomize...
In order to investigate the effect of agrophysiologic traits of bread wheat cultivars to planting date, the present research was conducted on the basis of split plots experiment based on randomized complete blocks design with three replication during 2012-2013 at the research farm of Khuzestan Agriculture and Natural Resources Research Station. Three planting date mid-October, mid-November and ...
in a field experiment, during three successive years of 2007, 2008 and 2009, the effects of planting pattern and high corm density on agronomic performance of saffron was investigated at the research station of ferdowsi university of mashhad. a complete randomized block design in a factorial arrangement of three replications being employed. treatments consisted of three corm rates of planting (...
Mohar pearl oyster Pinctada radiata is the dominant economic species of pearl oyster in the Persian Gulf, particularly along the Iranian coastal waters. As pearling has been banned since 2006, stocks of pearl oysters has not been investigated during these years. For this purpose, conditions of natural habitats and stocks of Mohar pearl oyster in its old catch sites were surveyed in the present ...
Relationship between specific surface area per unit volume and microstructure of seasonal snow cover
drought stress is considered as the most important environmental abiotic stress, affecting grain yield of crop plants especially in arid and semi arid regions. increasing and utilization of the genetic diversity can be a useful strategy in breeding for drought resistance. in this study, twenty iranian durum wheat landraces along with two check cultivars were evaluated in a randomized complete b...
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
Abstract In order to study the inheritance of grain yield and its components in bread wheat, two cultivars, Karchyya(drought and salinity tolerant) and Gaspard (sensitive to drought and salinity stress) were crossed.Parents together with F1, F2, F3, BC1and BC2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.Grain weight per...
